Documented cause
Solyndra developed cylindrical thin-film solar panels claiming advantages in rooftop installation and low-light performance. The company raised $970M including a $535M loan guarantee from the US Department of Energy under the Obama administration's clean energy initiative. Chinese manufacturers flooded the market with conventional silicon panels at dramatically lower prices in 2010-2011, making Solyndra's technology economically unviable. Solyndra filed Chapter 11 in August 2011 and became a focal point of political controversy about government-backed green energy investments.
Alternative account: Solyndra made cylindrical solar panels using copper-indium-gallium-selenide (CIGS) cells — a premium technology designed for flat commercial rooftops. The DOE granted a $535M loan guarantee in 2009. Chinese manufacturers, subsidized by the Chinese government, slashed crystalline silicon solar prices by 75% between 2008 and 2011. Solyndra's cylindrical panels became uncompetitive almost overnight. The company laid off 1,100 employees and filed Chapter 11 in September 2011.
Lesson
“Government backing accelerates the build-out but cannot protect you from a competitor with lower structural costs. Validate your cost curve against the most aggressive competitor scenario before accepting a $535M government loan.
Alternative account: Any cleantech business model that is competitive only within a specific commodity price range must explicitly model the downside scenario where that range is disrupted by state-subsidized competition. Solyndra's investors and the DOE both failed this test.”
